Which diagram shows a hazard warning line?

Why this is the answer

You need to know the difference between the normal centre line and a hazard warning line. If there's a hazard ahead, the markings are longer and the gaps shorter. This gives you advance warning of an unspecified hazard.

Why the other answers don't fit

B
— Short marks with long gaps is the ordinary centre line. On a hazard line the paint is longer than the gap.
C
— A single yellow line along the kerb controls waiting at set times. Kerb markings warn of no hazard.
D
— Double yellow lines mean no waiting at any time — a parking rule, not a warning about the road ahead.

Where this comes from
